Tags should retain case, and should not be snake cased.
Easiest way to do this is to snake before converting tag
list as while that affects the keys of the boto3 tag lists,
it doesn't affect the values. Need to use `tag_value_key_name`
and `tag_name_key_name` following recent change to
`boto3_tag_list_to_ansible_dict`, which used to handle both
`key`/`Key` and `value`/`Value`
* Add new helper function for comparing AWS tag key pair dicts. Also modify boto3_tag_list_to_ansible_dict function to be more generic when looking for key names because AWS sometimes uses 'Key', sometimes 'TagKey' and who knows what the future holds! Fixed modules to work with changes.
* Review changes
* Add some more doc to GUIDELINES for tags and fix var name for snaked values in ec2_group_facts
